Problems solved by technology

At present, there are many problems when lifting, moving and restoring the cover: 1) Firstly, it is time-consuming and laborious for the operation and maintenance personnel to lift and carry the cover, and they directly contact the hard and rough cover, often scratching their hands, etc. , people are vulnerable to injury; 2) secondly, the manual lifting and handling cover plate is easy to fall off and damage the cable; 3) the current tools are simple and clumsy, and the cover plate is easy to be damaged; 4) the last cover plate is heavy, and female employees and the elderly cannot Participate in lifting and handling work
In the process of lifting the cover plate, due to manual operation, accidents such as personal injury, damage to the cover plate, and cover plate falling off often occur

Abstract

The invention discloses a movable cable cover plate crane carriage of a transformer substation. The movable cable cover plate crane carriage comprises a main frame, an upper frame, a hand winch, a pull rope and hooks. The bottom of each stand column among four stand columns is provided with a universal wheel capable of driving the crane carriage to move and automatically steering. The upper frame comprises two stand frames and a top rod. The hand winch is fixed to the middle of the top rod. The left end and the right end of the top rod are respectively provided with a fixed pulley. The pull rope is wound on the hand winch. The two ends of the pull rope are wound around the fixed pulleys at the two ends of the top rod respectively, and the tail ends of the pull rope are respectively and fixedly provided with one hook. The movable cable cover plate crane carriage of the transformer substation has the advantages of being capable of quickly and conveniently lifting up cable cover plates, reducing lifting time, moving time and cover plate recovery time in the process of inspecting a cable channel, eliminating potential safety hazards in the process of moving the cover plates, and the like.

Description

technical field [0001] The invention relates to a lifting trolley for a movable cable cover plate of a substation. Background technique [0002] The "Substation Management Regulations" of the State Grid stipulates: "Before the rainy season, conduct a comprehensive inspection and dredging of the drainage facilities in the basement, cable trenches, cable tunnels and factory areas that may accumulate water, and take measures to prevent water ingress and drainage", "Rain Finally, check the water accumulation in the basement, cable trench, cable tunnel, etc., and drain it in time. When the moisture in the equipment room is too high, do a good job of ventilation.” Once the cable trench accumulates sewage for a long time, the insulation strength of the cable will be reduced, which may lead to single-phase high-voltage cables. Grounding or multi-phase faults and tripping will reduce the reliability of power supply; at the same time, it will cause one or more points of the secondary ...
